Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.

Example 1

Referring to fig. 1, 2 and 3, the present embodiment provides an adaptive mask, which includes a mask base layer 1, an inner module 2, an inner module 3, a frame 4 and a strap 5. The side close to the face of the user when worn is defined as the inner mask base layer 1 which is the carrier of the adaptive mask. In this embodiment, the mask base layer 1 may be made of a transparent and lightweight material, such as plastic, which can reduce the overall weight of the adaptive mask, and is not prone to fluffing after being worn for a long time, and is easy to clean. A photochromic layer may be provided on the outer surface of the mask base layer 1. Photochromic refers to the change in molecular structure of certain compounds under the action of light of a certain wavelength and intensity, and the change is generally reversible. Therefore, different colors and patterns can be presented on the surface of the mask due to different ambient light through the photochromic layer in the embodiment, so that the identification degree of the user wearing the mask is increased. The shape of the outer edge of the mask base layer 1 can be rectangular, and is similar to the shape of the existing medical surgical mask. Of course, the mask base layer 1 in other embodiments may also be of a funnel shape, similar to the shape of the existing N95-grade protective mask. At least one through hole 11 is formed on the mask base layer 1, in the embodiment, the number of the through holes 11 formed on the mask base layer 1 is preferably two, and the two through holes 11 can be symmetrically distributed on the mask base layer 1. In this embodiment, in order to allow the air flow when the user wears the mask and breathes to pass through only the through hole 11, the mask base layer 1 may be made of a material impermeable to air, and the mask base layer 1 may be waterproof and dirty-resistant.

The internal module 2 comprises a sensor module 22, a processor module 23, and at least one air filtration module 21.

Referring to fig. 4 and 5, each air filter module 21 is installed in each through hole 11. Each air filtration module 21 comprises a plurality of layers of filter sheets 211. The filter sheet 211 serves to filter the air flow passing through the through-holes 11. Since it is mentioned above that the air flow can only pass through the through holes 11 when the user wears the mask to breathe, the multi-layer filter sheet 211 can effectively filter most of the particles in the air flow when the air flow passes through the through holes 11. In this embodiment, the multiple filter sheets 211 in each through hole 11 may be arranged side by side at equal intervals. The shape and size of each filter sheet 211 are kept in conformity with the end face shape of the through-hole 11. The material of the filter sheet 211 is preferably a melt-blown nonwoven fabric, and droplets containing harmful particles such as bacteria and viruses or air may be electrostatically adsorbed on the surface of the filter sheet 211 made of the melt-blown nonwoven fabric and may not permeate therethrough.

The sensor module 22 is used for detecting the content one and the content two of at least one kind of particulate matters in the air flow before and after passing through any through hole 11 in a unit time in real time. It should be noted that each kind of particulate matter has a corresponding content, and the content of different particulate matters in the air is different, and the sensor module 22 in this embodiment can detect one kind of particulate matter, such as a pathogen or a virus that prevails in the current season. In other embodiments, the sensor module 22 may also detect two or more different types of particulate matter. Can select the gauze mask that can detect different kinds of particulate matter to user's actual demand.

Referring to fig. 6, in the present embodiment, since the air filtering modules 21 in the through holes 11 are arranged uniformly, the air filtering effect can be regarded as the same, that is, the filtering effect of the whole adaptive mask is the same, so that the sensor module 22 can be arranged near only one of the through holes 11. The sensor module 22 may be an electrochemical sensor or other types of sensors known in the art. Of course, in other embodiments, a plurality of sets of sensor modules 22 may be provided, and fig. 6 shows that in other embodiments, more than one set of sensor modules 22 is provided, and by providing a plurality of sets of sensor modules 22, a plurality of sets of different data values can be detected in a unit time, so that a plurality of sets of data values can be fitted and averaged, and the final result is more accurate than that of a single set. The sensor module 22 may include a first sensor unit 221 and a second sensor unit 222.

The first sensor unit 221 is used for detecting the content one of at least one kind of particulate matters in the air flow before passing through any one through hole 11 in a unit time in real time.

The second sensor unit 222 is used for detecting the content two of at least one particulate matter in the air flow after passing through any through hole 11 in a unit time in real time.

The processor module 23 is used for calculating a filtering efficiency in real time according to the content one and the content two. The processor module 23 is also used for storing the data of the content one, the content two and the filtering efficiency and transmitting the data to a terminal device 8. In the present embodiment, the processor module 23 may include a computing unit 231, a storage unit 232, and a data transmission unit 233.

The calculating unit 231 is used for calculating the filtering efficiency in real time according to the content one and the content two. The calculation formula of the filtering efficiency eta is as follows:

wherein G is₁The content of at least one kind of particles in the air flow before passing through any through hole in a unit time is one; g₂The content of at least one kind of particles in the airflow after passing through any through hole in one unit time is II. G in the present example₁And G₂The content is the mass or quantity (unit: mg/h or particles/h) of the particulate matters in the air flow at the inlet and the outlet of the filter module in unit time, and the filtering efficiency eta can be used for representing the air filtering effect of the filter module by calculating. In other embodiments, the filtering effect of the filter module may also be characterized by calculating the penetration force or the purification coefficient.

The storage unit 232 is used for storing data of the content one, the content two and the filtering efficiency. The data transmission unit 233 is used to transmit the data of the three stored in the storage unit 232 to the terminal device 8. Here, the terminal device 8 may be a smart phone of the user or a smart watch of the user. The gauze mask in this embodiment can carry out wireless connection with terminal equipment 8 for the person of wearing can know the protective conditions of self-adaptation gauze mask in real time through terminal equipment 8, and current air quality.

In some embodiments, the processor module 23 may also include a timing unit 234. The timing unit 234 is used to drive the processor module 23 to start every preset time. In this embodiment, the timing unit 234 may control the processor module 23 to start every minute, obtain the first content and the second content, and calculate the filtering efficiency. Of course, in other embodiments, unnecessary power loss may be reduced by setting the timing unit 234 to keep the processor module 24 in the sleep state.

The inner module 3 is installed inside the mask base layer 1. The inner module 3 includes a nano-power generation module 31 and an energy storage module 32.

The nano power generation module 31 is used for converting mechanical energy in airflow generated when a user wears the self-adaptive mask to breathe into electric energy. In this embodiment, the shape of the outer edge of the nano-power generation module 31 may be consistent with the shape of the mask base layer 1, and the nano-power generation module 31 and the mask base layer 1 may be parallel to each other, so that it is convenient to install in the frame 4 and more closely. The nano-power generation module 31 may include a first friction layer, a second friction layer, a first conductive layer, and a second conductive layer. When a user wears the mask to breathe, the first friction layer and the second friction layer can be continuously contacted and separated due to air flow generated by breathing, so that an electric signal is generated, and the electric signal can be conducted through the first conducting layer and the second conducting layer. Therefore, the user can generate electric energy by breathing with the mask, and the generated electric energy can be transmitted to the energy storage module 32 for storage. The power generation principle of the nano power generation module 31 is similar to that of the existing nano power generator, and is not described in detail herein.

The energy storage module 32 is used for storing the electric energy generated by the nano power generation module 31. Wherein the energy stored by the energy storage module 32 is used to power the processor module 23 and the sensor module 22, respectively. In this embodiment, the electrical energy stored by the energy storage module 32 is used to power the processor module 23 and the sensor module 22, respectively. The energy storage module 32 may include a first energy storage unit 321 and a second energy storage unit 322. The first energy storage unit 321 is used for storing electric energy generated by the nano power generation unit and supplying power to the internal module 2, so that self-driving of the mask can be realized when a user wears the mask and breathes, and the mask is environment-friendly. And when the electric energy stored in the first energy storage unit 321 is not enough for the internal module 2 to continue to operate, the second energy storage unit 322 can be used to directly supply power to the internal module 2. The second energy storage unit 322 can be a button cell, and is small in size, light and convenient to detach and replace.

Frame 4 is a frame of gauze mask basic unit 1, and frame 4 in this embodiment can adopt plastic material, preferably aluminium strip, when receiving external force, and frame 4 can produce plastic deformation (permanent deformation) to realize around gauze mask basic unit 1 with the seamless connection of user's face, improve the driving fit degree that the gauze mask wore, increase the protectiveness of gauze mask. In the manufacture process of the self-adaptive mask of the embodiment, the mask base layer 1, the internal module 2 and the internal module 3 can be detachably mounted inside the frame 4. More specifically, the air filtering module 21 in each through hole 11 can be conveniently detached from the mask base layer 1, so that the air filtering module 21 can be conveniently replaced, and the filtering effect of the mask can be maintained regularly. In addition, sensor module 22, controller module and nanometer power generation module 31 are all detachable installation also on gauze mask basic unit 1, can break away from in making each part of gauze mask basic unit 1 like this, because gauze mask basic unit 1 has waterproof dirt resistance, can regularly clean gauze mask basic unit 1, dispel pollutants such as the bacterium on gauze mask basic unit 1 surface, virus, droplet to keep gauze mask basic unit 1's sanitary degree, improve the security of self-adaptation gauze mask. Of course, in other embodiments, the components of the adaptive mask may be manufactured into an integrated structure, which may improve the sealing performance and the structural reliability of the mask.

In the present embodiment, the number of the straps 5 may preferably be two. Of the two straps 5, both ends of each strap 5 may be fixed to both sides of the frame 4, respectively.

Example 2

Referring to fig. 7, the difference between the present embodiment and embodiment 1 is that, on the basis of embodiment 1, the adaptive mask may further include an indicator light 1. The processor module 23 may be further configured to obtain a preset safety interval (a, b) corresponding to the content two, compare the content two obtained in real time with two thresholds a, b of the preset safety interval (a, b), and make the following decision:

(1) and when the second content is smaller than the threshold value a of the preset safety interval (a, b), judging that the quality of the air currently inhaled into the human body by the user is at a safety level, and controlling the indicator lamp I6 to display green.

(2) And when the second content is larger than the threshold value a of the preset safety interval (a, b) and is smaller than the threshold value b, judging that the quality of the air currently inhaled into the body of the user is at a light pollution level, and controlling the indicator lamp to display yellow.

(3) And when the second content is larger than the threshold value b of the preset safety interval (a, b), judging that the quality of the air currently inhaled into the human body by the user is at a severe pollution level, and controlling the indicator light I6 to display red.

The first indicator light 6 in the embodiment can be arranged on one side, away from the nanometer power generation unit, of the mask base layer 1, and a user can sense the color and the color change of the first indicator light 6 when wearing the mask. Through setting up pilot lamp 6, the user can also obtain the approximate level that the content two of at least one kind of particulate matter is in the air current after filtering air module 21 in a unit interval through observing pilot lamp 6 on the gauze mask under the circumstances that does not hold terminal equipment 8, namely the user can observe pilot lamp 6 and judge whether the air quality that oneself is currently inhaled in vivo is up to standard to can select the time of leaving the environment that is currently located, thereby avoid inhaling too much air that is not up to standard and be harmful to user's health.

Example 3

Referring to the drawings, in this embodiment, on the basis of embodiment 1 or embodiment 2, the adaptive mask may further include a second indicator light 7. It should be noted that in some embodiments, only the second indicator light 7 may be provided, and in other embodiments, the first indicator light 6 and the second indicator light 7 may be provided at the same time. The processor module 23 is further configured to obtain a preset safety interval (c, d) corresponding to the content one, compare the content one obtained in real time with two thresholds c, d of the preset safety interval (c, d), and make the following decision:

(1) and when the first content is smaller than the threshold value c of the preset safety interval (c, d), judging that the air quality in the current environment of the user is at a safety level, and controlling the second indicator light 7 to display green.

(2) And when the content I is larger than the threshold value c of the preset safety interval (c, d) and is smaller than the threshold value d, judging that the air quality in the current environment of the user is at a light pollution level, and controlling the indicator lamp II 7 to display yellow.

(3) And when the content I is larger than the threshold value d of the preset safety interval (c, d), judging that the air quality in the current environment of the user is at a severe pollution level, and controlling the indicator light II 7 to display red.

Like embodiment 2, the second indicator light 7 in this embodiment may also be disposed on a side of the mask base layer 1 away from the nano-power generation unit, and in the case of disposing the second indicator light 7 and the first indicator light 6, the second indicator light 7 and the first indicator light 6 may be disposed at two ends of the same side of the mask base layer 1, and the two indicator lights may be disposed in bilateral symmetry. Through setting up indicator lamp two 7, the user can also obtain the approximate level that the content one of at least a kind of particulate matter was located in the air current before filtering gas module 21 in a unit interval through observing indicator lamp two 7 on the gauze mask under the circumstances that does not hold terminal equipment 8, namely the user can observe indicator lamp two 7 and judge whether reach standard to the air quality in the environment that oneself is present to can select the time of leaving the environment that is present. The mask has the advantages that the mask has high filtering effect, so that even if a user is in an environment with serious pollution at present, the signal reflected by the first indicator lamp 6 can still be in a safe state, and the air inhaled by the user is safe and healthy. However, if the user is in such an environment for a long time, the mask may absorb and filter a large amount of harmful particles for a long time (compared with the normal safe state), which may increase the service life of the mask. Therefore, the second indicator light 7 capable of reflecting the air quality level in the environment is arranged, the user can directly obtain the air quality of the current environment through observing the second indicator light 7, the time of leaving the current environment is selected in a short time, the user can be prevented from inhaling more harmful gas to damage the health, and the phenomenon that the service life of the mask is shortened due to the fact that the mask is exposed in the heavily polluted environment for a long time can be avoided.
